Nope, not at all, sorry. I saw a show last year on Greek tv (it was similar to those Animal Planet/Discovery/NatGeo shows) where a bunch of guys (biologists, I am sure) had so much fun catching sharks, drill holes in their fins, attaching transsponders to them, (trying to) release them, that I got sick to the stomach. They were more busy with the camera than with the wellbeing of the animals who were struggling to escape from the manmade release system which consisted of some ropes. All ‘for research purposes’ of course… I don’t speak “sharkish” but I was pretty sure that I could read the stress from their bodies (the sharks bodies, that is). Wouldn’t be surprised if the ‘research’ results would be tainted by the stress levels of the animals (do they act the same with a transponder drilled to their backs?).
